SIMLR: Machine Learning inside the SIR Model for COVID-19 Forecasting

open access: yesForecasting, 2022
Accurate forecasts of the number of newly infected people during an epidemic are critical for making effective timely decisions. This paper addresses this challenge using the SIMLR model, which incorporates machine learning (ML) into the epidemiological ...

Probabilistic knowledge-based characterization of conceptual geological models

open access: yesApplied Computing and Geosciences, 2021
The construction of conceptual geological models is an essential task in petroleum exploration, especially during the early stages of investment, when evidence about the subsurface is limited.

Generalized Permutohedra from Probabilistic Graphical Models [PDF]

open access: yes, 2017
A graphical model encodes conditional independence relations via the Markov properties. For an undirected graph these conditional independence relations can be represented by a simple polytope known as the graph associahedron, which can be constructed as

Deep Probabilistic Graphical Modeling

open access: yesCoRR, 2020
Probabilistic graphical modeling (PGM) provides a framework for formulating an interpretable generative process of data and expressing uncertainty about unknowns, but it lacks flexibility. Deep learning (DL) is an alternative framework for learning from data that has achieved great empirical success in recent years.

Marginal and simultaneous predictive classification using stratified graphical models [PDF]

open access: yes, 2014
An inductive probabilistic classification rule must generally obey the principles of Bayesian predictive inference, such that all observed and unobserved stochastic quantities are jointly modeled and the parameter uncertainty is fully acknowledged ...

On a Class of Tensor Markov Fields

open access: yesEntropy, 2020
Here, we introduce a class of Tensor Markov Fields intended as probabilistic graphical models from random variables spanned over multiplexed contexts. These fields are an extension of Markov Random Fields for tensor-valued random variables.

An Order-Independent Algorithm for Learning Chain Graphs

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference, 2021
LWF chain graphs combine directed acyclic graphs and undirected graphs. We propose a PC-like algorithm, called PC4LWF, that finds the structure of chain graphs under the faithfulness assumption to resolve the problem of scalability of the proposed ...

Probabilistic inference in general graphical models through sampling in stochastic networks of spiking neurons. [PDF]

open access: yesPLoS Computational Biology, 2011
An important open problem of computational neuroscience is the generic organization of computations in networks of neurons in the brain. We show here through rigorous theoretical analysis that inherent stochastic features of spiking neurons, in ...

Bayesian graphical models for computational network biology

open access: yesBMC Bioinformatics, 2018
Background Computational network biology is an emerging interdisciplinary research area. Among many other network approaches, probabilistic graphical models provide a comprehensive probabilistic characterization of interaction patterns between molecules ...
